The mileage is irrelevant to me, they are great cars, there was, not sure if it's still there, a grey one in Newcastle area, think it's a one owner with 60k ish mileage, has full history, some with an Indy, "westfields " who are Lexus specialist, they are excellent, and that wouldn't worry me at all, they have looked after all my lexus's in the past. Think that was 19k, mine has 3 previous owners, previous to me only a year, think a lot of people have the "always wanted one"......me too, but I don't want to part with mine EVER, good luck with your demons
